harmonic theory III

melodic minor

If the 6th step of the harmonic minor scale is increased by a halftone, the melodic minor scale arises. This scale got a dominat sept accord on the 5th step. Because of its missing 3-halfton-step it sounds a bit mor round than harmonic minor.
Accords and options are changed.

1	A C E G#	A-^maj7	9 4 6	1	9	b3	4	5	6	#7	1	dor #7
2	B D F# A	B-⁷	b9 4 6	1	b9	b3	4	5	6	7	1	dor b9

7	G# B D F#	G#-^7/b5	b9 b4 b6	1	b9	b3	b4	b5	b6	7	1	lok b4

The quardcadence can be played like:

A-^maj7

D⁷

G#-^7/b5

C^maj7/#5

F#-^7/b5

B-⁷

E⁷

A-^maj7

A-minor is the tonal center ( tonica ).

harmonic - major

A new scale arises if the 6th step of a major-scale is decreased by a halftone. Its called harmonic major.

Stepcords - harmonic major. Scalename is a shor form of the church modus added with alterated tones.

The quardcadence is

A^maj7

D-^maj7

G#-^b7/b5

C#-⁷

F^maj7/#5

B-^7/b5

E⁷

A^maj7
